58 Beastlord with tier 1 journeyman tank merc and 58 spell pet. First time ever doing and epic quest line.
Was very close but he finally started walking at 3% because my merc was just below 10%
My pet and merc didn't find their way to me when the spirit engaged for about 10 seconds, so when you run up from the scout wait for your team.
But he comes from the shadowmens direction like posted by others, just go SW wait for your team then head a little south and you'll see him coming. GL
